    Default under engine inspection hatch

    just remved the hatch from my 03 2.2 dti including the bits that go up the arches to get to the aux belt as its squeeking, im no expert but i couldnt believe all the crud that gets in there and the sub frame looks rusty like its had alot of water on it, is it a bad idea to remove the under tray and maybe give the subframe a lick of paint?

    I noticed the same thing when I removed my undertray a couple of weeks ago to replace the belt tensioner. I have quickly treated the worst of the rust but it needs a better job when I have more time.

    I think the water splashed up off the road and condensation from the air-con pipes both site on the undertray and rust through the subframe. Mine was most rusted in the rear offside corner which is where the condensation from the air-con pipes that are in with the wiper linkage seems to drain straight on to.

    I was considering either (a) drilling some drain holes in the undertray, (b) seeing if it's possible to put some spacers between the subframe and the undertray (so the subframe is above the water), or (c) leaving the undertray off (it's only for noise regulations so not vital) and doesn't apparently make that much difference to the noise level if left off.

    I wouldn't, think it aides engine cooling, and protects all your under engine casings etc.

    Had my 2.2DTi for 2 years, the undertray was missing when I bought it and I've had no issues with not having one.

    TBH, I am erring towards modifying the undertray rather than removing it - as stated above, it may have uses other than meeting drive-by noise regulations.
